Title: Pressure reducing devices
IPC: G05D16/06
Filed: 1972-09-27
Abstract: 1340943 Valves GURTNER SA 27 Sept 1972 [1 Oct 1971 19 July 1972] 44669/72 Heading F2V A valve comprises a valve member 7 urged to the closed position by a spring 10 and fluid pressure at the inlet 2, and urged to the open position by a loading spring 26 acting on a diaphragm 13 which is subject to the outlet pressure in chamber 12, the loading spring being selectively made non-operative by a control knob 16. Rotation of the control knob 16 from a "non-operative" position in which lugs 24 of the spring cage 25 rest on ledges 23, causes rotation of the cage and spring to an "operative" position (shown in Fig. 1) in which the spring 26 is free to act on the diaphragm. Transmission of the rotation takes place via a splined rod 22 and complementary aperture which has sufficient clearance to enable a small counter-rotation of the knob so that the spring 26 is not subject to torsion.

Title: Monitoring a gas stream
IPC: G01N31/00
Filed: 1963-11-20
Abstract: A material is analyzed by subjecting it to a variation in temperature whilst exposing it to a continuous flow of a mixture of gases of constant composition, at least one of the gases being reactive with the material and sensing the changes that occur in the composition as a function of temperature.  A thermal conductivity detector may be used to measure the change in composition of the gas mixture which mixture may comprise a gas which is inert or less reactive than the other gas.  The temperature variations may be decreasing, increasing or alternating.  In a specific embodiment (Fig. 1, not shown) a metal ore is reduced by a hydrogen stream in a furnace which is controlled by a temperature programmer.  The effluent stream is dried before passing to a detector cell where its hydrogen content is compared with a portion of the original gas stream which has by-passed the furnace and the results recorded.  In another specific embodiment (Fig. 2, not shown) a mixture of nitrogen and hydrogen is passed through a detector and on to a furnace containing a sample e.g. a metal oxide or salt which is to be reduced.  The effluent gas stream is led out through the initial detector and the effluent hydrogent content compared with the original stream.  A great number of specific applications of this method are disclosed.  Thus in decomposition reactions e.g. calcining carbonates, the temperatures of incipient, maximum and complete decomposition may be determined. Mixtures of halogens and helium or oxygen and helium may be used for halogenation and oxidation reactions respectively, whilst corrosion hydrogen embrittlement, adsorption/desorption phenomena e.g. Pd + H2 may also be studied.  The reduction of metal oxides and ores with hydrogen or carbon may be studied e.g. NiO/H2 + N2 and Fe2O3/H2 + N2. Quantitative investigations to characterise metal oxides, nitrates and chlorides of known reduction points may be accomplished wherein the hydrogen uptake is a measure of a component present in a mixture. It is stated that surface areas, porosity and catalytic activity may also be investigated using the above technique.

Title: Improvements in or relating to power transmissions

Filed: 1968-09-28
Abstract: 1,222,405. Hydrostatic transmissions. SPERRY RAND CORP. 28 Sept., 1968, No. 46182/68. Heading F2D. A hydrostatic transmission for a vehicle includes pump and motor units connected to supply and return conduits, an engine driving the pump, a sensing valve providing a control signal varying in response to engine speed and torque, i.e. fluid supply rate and pressure, and a by-pass valve normally diverting fluid from the supply to the return conduit in response to the signal to regulate the flow to the motor and vary its speed over a range of engine speed as a function of engine torque for smooth engagement and disengagement of the transmission. System details.-As shown an engine driven fixed displacement swashplate pump 16 supplies a variable displacement motor 22 provided with a forward and reverse selector valve 38 and an hydraulic servo 36 controlling the swashplate 44. The spool type by-pass valve 26 has connections 124, 126 with the motor supply and return lines, and a further connection 142 with the pump pressure line 28. A compensator valve 34 of similar type has a connection 19 with the pump pressure line and a further connection 170 with the servo cylinder 36, the fluid supply for which is provided by a make-up pump 32. The sensing valve 24, the pressure drop across which provides the control signal, consists of a spring-loaded tapered pin 100, movable under the restraint of limit stops 106, 108 in a tapered throat 88, the ends of which are respectively connected to the pump pressure line 28 and motor supply line 28b. A sensing port 112 communicating with a cross-connection 144 between the by-pass and compensator valves 26, 34. Operation.-Upon adjustment of selector valve 38 and engine throttle 20 pressure in pipe-line 28 increases to raise the tapered pin 100 of sensing valve 24 against its loading spring. The pressure drop across valve 24 operates by-pass valve 26 which progressively closes until full communication is established by lines 28, 30 between the pump and motor. When the pressure drop reaches a predetermined value compensator valve 34 is moved to the left to establish communication through lines 158, 170 between make-up pump 32 and the motor servo 36 to vary the inclination of the swash-plate 44. Engine torque variation under load varies the setting of sensing pin 100 to regulate compensator valve 34 and effect appropriate adjustment of the displacement and speed of motor 22.

Abstract: 930,358. Two-part couplings. HARVEY HUBBELL Inc. Dec. 28, 1961 [April 19, 1961], No. 46517/61. Class 38 (1). In a plug-and-socket cable connector of the type in which after insertion of the blades the plug is rotated to lock it to the socket, a key, intended to prevent connection of non voltagecorresponding plugs and sockets, mates with a hole in the socket, the key being mounted so as to allow the locking rotation. As shown in Figs. 1 and 2, L-shaped blades 23, 24 fit into slots 21, 22, contact being made with contacts 6, Fig. 5. The plug is then rotated so that the shoulders 28, 29 of the blades hook under the front face of the socket, at the same time maintaining contact. The key 48 is mounted on the plug so that it can be rotated against a frictional force when the connector is locked and unlocked. In order to polarize the connector one plug blade 24 may have an offset rib 42 at one edge extending for the same depth as the locking end portion 27, and the socket in this case has a correspondingly shaped slot 22, 43 to allow the insertion of the plug. The connecting wires are pressed against the contact members in both plug and socket by insulating end caps 2, 31, contained in metal end caps 3, 32 to which longitudinal compressing screws are threaded. Both plug and socket are also provided with strain relief clamps 8, 39, held in position by legs 10, 40 trapped inside the metal end caps 3, 32. Variously shaped keys are described.

[Also in Division F2] A sleeve valve for feeding powdered materials to a bag filling machine is formed with a single rubber sleeve 30 which is secured at 37 and 38 to casing 25 and is operated by air pressure at 29. Spider 45 is positioned inside the casing and central thereof so that when air is admitted at 29 the sleeve 30 is pressed inwards, the three arms of the spider dividing the sleeve into three elements which seal by pressing against the arms of the spider till the fall of material through casing 25 is terminated.
